House Russia investigators are planning to call on Brad Parscale, the digital director of President Donald Trump's campaign, as the congressional and federal probes dig into any possible connections between the Trump digital operation and Russian operatives, congressional sources said this week.

The House Russia investigation is planning to send an invite to Parscale soon, as they begin scheduling witnesses over the summer, sources said. The Senate intelligence committee is also interested in how Russian bots were able to target political messages in specific districts in critical swing states, although it is not clear if Parscale will be called before the Senate panel as well.

The news from the House comes as federal investigators have dug into Jared Kushner's role overseeing Trump's data operation -- although he has not been identified as a target of the probe. Kushner is expected to talk soon with Senate investigators about the campaign's data operation.

Parscale played a critical role behind the scenes on the Trump campaign, directing online spending and voter targeting with the use of a highly sophisticated data bank built by the Republican National Committee. Parscale, was running the Trump Organization's digital operation in early 2015, when he was hired onto the Trump campaign -- months before Trump officially announced his bid.

4. This SHOULD be the biggest political news of the day. But it isn't.

Bannon is under investigation by Mueller. Obstruction. This according to Claude Taylor, who also stated that Bannon's been physically threatening WH staff. That, in itself, if true, can be framed as Obstruction. We'll see.

On Oct. 19, as the third and final presidential debate gets going in Las Vegas, Donald Trump’s Facebook and Twitter feeds are being manned by Brad Parscale, a San Antonio marketing entrepreneur, whose buzz cut and long narrow beard make him look like a mixed martial arts fighter. His Trump tie has been paired with a dark Zegna suit. A lapel pin issued by the Secret Service signals his status. He’s equipped with a dashboard of 400 prewritten Trump tweets. “Command center,” he says, nodding at his laptop.

Parscale is one of the few within Trump’s crew entrusted to tweet on his behalf. He’s sitting at a long table in a double-wide trailer behind the debate arena, cheek to jowl with his fellow Trump staffers and Reince Priebus, chairman of the Republican National Committee. The charged atmosphere and rows of technicians staring raptly at giant TVs and computer screens call to mind NASA on launch day. On the wall, a poster of Julian Assange reads: “Dear Hillary, I miss reading your classified emails.”

10:04 p.m.: Trump blames Clinton for $6 billion that went missing during her tenure at the State Department (actually a bookkeeping error). “Hit that hard,” shouts Jason Miller, Trump’s senior communications adviser. Parscale already has: “Crooked’s top aides were MIRED in massive conflicts of interest at the State Dept. WE MUST #DrainTheSwamp.”
